A program operating apparatus comprises a body unit and a memory unit, attachable to and detachable from the body unit, for storing an application program. The memory unit stores sales area data indicating sales areas of the memory unit. The body unit stores sales area data indicating sales areas of the body unit. When executing software of the memory unit, there are checked the sales area data of this memory unit and the sales area data of the body unit. Thus, the memory unit sold in areas exclusive of the sales areas of the body unit is prevented from operating on that body unit. Similarly, the body unit sold in areas exclusive of the sales areas of the memory unit prevents an execution of the memory unit.
